If you can fill a one gallon container in under 30 seconds you should be good for a 11 second car, BG use to have a flow chart on thier website saying that a nine second car needed one gallon in or under 20 seconds, 10 second was, maybe, 25 seconds My memory is horrible, maybe someone else on here knows of another site that has flow numbers for testing and will post a link or say where to go to The comment on the needles and seats is very apprpriate, I have gone through that on many carbs, a .110 needle and seat would starve the motor according the wide ban and a .120 was more than enough Good luck, fix it before you burn the motor up In other words lift if it noses over
